Waterstop Selection Water Pressure / Cover Depth / Stress Rule of Cover Depth The data in the tables on water pressures and the resulting movement gives the general application range in which the waterstops can be used without additional testing requirements. Shear strains in the y direction (transverse longitudinal to the waterstop) are limited to the dimensions of the nominal joint width w nom. If the shear strains are greater, then additional measures are required. The different forms of waterstops are to be selected as detailed in DIN V 18197. If the water pressure and/or resulting movement value is exceeded, the values applicable to the specific use should be defined on the basis of specific references, calculations or tests, with allowance for all of the actual influences and stresses anticipated. As applicable to internal waterstop froms: Concrete cover embedment depth Or Total waterstop width a Component thickness Anchorage Depth Reinforcement Clearance Component thickness Waterstop width a Embedment depth Cover Externally fixed waterstops and finishing waterstops can be selected without considering the member thickness. The anchorage depth/concrete cover of the anchor ribs / sealing ribs must be mm minimum. Nominal joint widths Temperature range The clearance between waterstop and reinforcement shall be at least mm. The nominal joint width is: Internal expansion waterstops External expansion waterstops Waterstops for capping joints w nom = or mm w nom = mm w nom = in accordance with the profile clearance (1,,, 4 mm) For a greater nominal joint width or compression joints subject to shear stresses, internal expansion waterstops with encased centre-bulb are used. The service temperature range (waterstop temperature) is: For pressurised water: For non pressurised water: - C to +4 C, - C to +6 C. 6 Tricosal Waterstops - Elastomer 6/12
Special stresses and exposure Exposure to Different Temperatures and Chemical Agents System Information General Factory Produced Jointing Pieces For special stresses and exposures due to different temperatures and/or chemical mediums outside the substances or situations specifically defined in DIN 433. Separate tests are always necessary. Where required other materials are available in addition to the standard SBR (styrene butadiene rubber). Tricosal Elastomer waterstops made from materials other than the standard SBR Grade are produced to order when required. They are not held in stock. Only butt joints should be formed on site with Tricosal Elastomer waterstops; the other junctions / joints should all be factory produced. The factory production of different waterstop systems and junctions reduces the joints required to be formed on site to a minimum. Special junctions or waterstopping systems can be factory produced for specific projects. Standard junctions for internal and external waterstops include Cross piece flat T-piece flat L-piece flat Cross piece vertical T-piece vertical L-piece vertical Standard joint profiles of exposed /finishing waterstops include Cross piece vertical inside T-piece vertical L-piece vertical L cross piece flat L-piece flat, cover slab Production of these profiles is preferably in 9, or in standard internal or external angles 6-175. Special junctions Combined junctions using different waterstop forms (as connections) e.g. form FM with AM, FM/FMS with steel sheet or AM with FAE. In the standard approach the preformed junctions / jointing pieces are built into the waterstopping systems. The sizes of the system components are dependent on the waterstop forms involved and the type and number of joints required. The normal maximum total length of waterstopping systems: up to 25 m maximum (total for all separate lengths). 7 Tricosal Waterstops - Elastomer 7/12

Handling As specified in DIN V 18197. - Careful transport and handling on site - Installation only at waterstop material temperatures C - Protection is required until the waterstopping system is fully cast in - Special care to be taken of free waterstop ends - Waterstops are to be cleaned before casting in Application Instructions Application As specified in DIN V 18197. - Internal waterstops are installed within the concrete section and clearance from the edge of the concrete being at least half the total width a of the waterstop. - External waterstops are installed flush with the external face of the concrete. Do not install on the top surface of horizontal or slightly sloping concrete. - Waterstops for capping joints are installed in the joint, set back by the dimension of any joint chamfer. If there are very high stresses or difficult concreting conditions, the waterstops can be supplied with additional injection hoses to additionally inject/grout the cast-in parts at a later date. 8 Tricosal Waterstops - Elastomer 8/12
Jointing on Site: Site Joints The Elastomer waterstops are butt jointed together by vulcanization, i.e. with added Tricosal rubber strips and the action of heat and pressure in a site vulcanizing equipment with moulds dependent on the profile used and longitudinal strain and specified vulcanizing parameters for the specific forms (temperature and time). Jointing with other vulcanizing agents without heat or using adhesives or adhesive tape is not permitted. Site joints must only be formed as stated in the vulcanizing instructions. Requirement: Minimum ambient temperature + 5 C and dry weather conditions. Site joints must be formed only by trained and qualified personnel. The key steps in the vulcanizing for all Tricosal Elastomer waterstopping forms FM/F, FMS/FS, FMS HS, AM/A, FAE are fully described in the detailed instructions. These key steps for site jointing complying with the vulcanizing instructions are: Cut the waterstop ends, straight and square Roughen the waterstop ends on the front, top and bottom Grind the steel plates until smooth, for FMS/FS Application of vulcanizing solvent, For FMS/FS also Apply 2 coats of bonding agent before application of vulcanizing solvent Plug the centre bulb with a foam stopper and Elastomer stopper from adhesion foil Apply the bonding agent on the front Bring together the waterstop ends and apply the tensioning harness Wrap in strip tape Wrap in strip tape 1 Sprinkle the wrapped joint with talcum release agent Place the prepared joint in the preheated vulcanizing equipment with the oulds for the form Vulcanize the butt joint for about 35 minutes Remove from the vulcanizing equipment Cool (by ambient temperature - do not use coolant) Vulcanizing Equipment After cooling for about half an hour, the joint is finished and may be fixed / installed / stressed. Further steps may be necessary dependent on the specific jointing requirements and the waterstop form. The vulcanizing instructions are enclosed with the vulcanizing equipment. All vulcanizing work is subject to the relevant local Health and Safety regulations and the Equipment and Materials Safety Information. Formation of these site joints takes about 1 2 hours of working time per joint dependent on the specific waterstop form and therefore this time must be scheduled and the work completed properly before the next operations proceed. - Vulcanizing equipment VG 45 for waterstops up to 4 mm total width - Vulcanizing equipment VG 6 for waterstops up to 5 mm total width - Moulds according to the profiles being used - Tensioning harness for longitudinal strain application Vulcanizing equipments are electrical appliances which are subject to standard regular safety checks which must be scheduled and arranged The vulcanizing equipments may only be used as described and according to all relevant regulations as stated in their operating instructions. 9 Tricosal Waterstops - Elastomer 9/12
